C86800 Bronze vs. CC763S Brass

Both C86800 bronze and CC763S brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 92% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is C86800 bronze and the bottom bar is CC763S brass.
